and the veins with another, and when the
lungs have afterwards been kept in a moist
state, it will be impossible for any one, who
examines them, either by the naked eye, or
by the microscope, to fail to observe that
the structure of the air-tubes is as distinct
and different from that of the true pulmonary
or parenchymatic tissue, as it is possible for
any two structures to be.
Whenever the smallest fragment of such
an injected lung is examined by the micros=
